Emergency dispatchers should be taught how to give compression-only CPR instructions over the phone, according to updated CPR guidelines for adults and children issued Tuesday by the American Heart Association.

Hundreds of thousands of people worldwide die every year from drowning. Yet efforts to figure out the best way to save them have been hindered by inconsistencies and confusion about how to report the details of these tragic occurrences and their eventual outcomes.

Cardiovascular disease is expected to kill about 23 million people a year globally by 2030, and the launch supports the AHA’s belief that everyone deserves to live a healthier, longer life.
